That's pretty much standard for all libraries on Windows, at least 
(Linux is a bit weirder; it may or may not be the case depending on how 
the symbol visibility is set -- essentially Windows defaults to hidden 
symbols and Posix defaults to visible symbols, though there has been a 
push recently to make it behave more like Windows).

You can often get away with it when there aren't singletons involved, 
but there can still be ABI problems if you have version mismatches 
between each side.
